Fine - i'll help you this once :P
For the map part you will need these;
Code:
#ACT
MAPMOVE mapname 5 10 [COLOR=DarkRed](5 10 = coords)[/COLOR]
MONGENEX mapname 5 6 Yob 6 7 [COLOR="DarkRed"](5 6 = coords / Yob = Mobname / 6 = range / 7 = amount of mobs)[/COLOR]
TIMERECALL 50 [COLOR=DarkRed](50 = minutes until teleported back)[/COLOR]
For the reward and mob killing part I suggest using an npc inside the room that checks if the room has no mobs inside and when it's true, gives a reward and teleports them out;
Code:
#IF
CHECKMAPMONCOUNT mapname = 0
#ACT
MAPMOVE mapname 5 10 [COLOR=DarkRed](5 10 = coords)[/COLOR]
GIVE rewarditem 2 [COLOR=DarkRed](2 = amount)[/COLOR]

Dark Red are notes - delete them from the script
